摘要
简要介绍了无功电能的各种测量方式,推导了跨相接线无功电度表(以下称作人为无功电度表)测量方法的误差公式,分析了三相电路对称性对这种无功测量误差的影响,提出了校验无功电度表时的注意事项。
This article introduced several measruing ways of reactive energy in brief,lead out the measuring error formula with artificial reactive watt meter,analyzed the affection of3-phase circuit symmetry to the artificial reactive measuring error,als o provided some notices for verifying reactive watt meter.
